A researcher from the University of Memphis was part of a team whose findings suggest that the rate of ice loss from the West Antarctic ice sheet has been slightly overestimated.
Dr. Robert Smalley of the U of M's Center for Earthquake Research and Information has been monitoring the movement of bedrock underneath the ice. As ice retreats, the bedrock recovers. The team's research suggests that the ice had not been thinning and retreating as much as previously believed.
Here is how the team's research was unique, according to the write-up on the Web site of KABC-TV in Los Angeles:

Now, for the first time, researchers have directly measured the vertical motion of the bedrock at sites across West Antarctica using the Global Positioning System. The results should lead to more accurate estimates of ice mass loss.
